Obviously, the principlesabove set forth are applicable to constructionsin which the planes of the transporter 1 and 9 are not horizontal.

I declare that what I claim is:

1. A tunnel containing an apparatus for transporting passengers ataccelerated speeds, wherein the visible lines appearing upon the sidesof the tunnel are inclined to the direction of travel of said apparatusby an angle whose direction and magnitude depend upon the direction andvalue of the acceleration of speed, so that the passengers transportedby said apparatus shall be given an optical illusion inducing them toautomatically displace their center of gravity towards the top of theimaginary plane resulting from the said optical illusion.

A tunnel containing an apparatus for transporting passengers ataccelerated speeds, wherein the vaulting of the tunnel is inclined tothe direction of travel of said apparatus by an angle Whose directionand magnitude depend upon the direction and value of the acceleration ofspeed, so that the passengers transported by said apparatus shall begiven an optical illusion inducing them to automatically displacetheircenter of gravity towards the top of the imaginary plane resultingfrom the said optical illusion.

3. A tunnel containing an apparatus for transporting passengers ataccelerated speeds, wherein the vaulting of the tunnel and the visiblelines appearing upon the sides of the tunnel are inclined to thedirection of travel of said apparatus by an angle whose direction andmagnitude depend upon the direction and value of the acceleration ofspeed, so that the passengers transported by said apparatus shall begiven an optical illusion inducing them to, automatically displace theircenter of grave it-y towards the top of the imaginary plane resultingfrom the said optical illusion.

In witness whereof I have hereunto set my hand. i
